The DESI will measure the velocities of about 30 million galaxies and quasars over five years. The LSST will collect more than 30 terabytes of data each night - for a decade. "The volume of datasets will be at least an order of magnitude larger," says Camille Avestruz, a KICP fellow. To keep up with an impending astronomical increase in data about our universe, astrophysicists turn to machine learning.
